This phenomenon could be observed for high speed or abrupt Doppler variations of clutter or target signal but also in case of target migration during the burst duration due to high range resolution. We propose new Radar Doppler processing assuming that each non-stationary signal in one burst can be split into several short signals with less Doppler resolution but locally stationary, represented by time series of Toeplitz covariance matrices. In Information Geometry (IG) framework, these time series could be defined as a geodesic path (or geodesic polygon in discrete case) on covariance Toeplitz Hermitian Positive Definite matrix manifold. For this micro-Doppler analysis, we generalize the Fréchet distance between two curves in the plane to geodesic paths in abstract IG metric spaces of covariance matrix manifold. This approach is used for robust detection of target in case of non-stationary Time-Doppler spectrum (NS-OS-HDR-CFAR).","PeriodicalId":376019,"journal":{"name":"2015 European Radar Conference (EuRAD)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131921160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regions of negative differential reflectivity have commonly been observed but are still yet to be explained physically. There are hypotheses that suggest common debris alignment and/or dominant scattering from objects with high radar-cross-section (RCS) values, but they are extremely challenging to verify due to the danger within tornadoes. It is, however, possible to numerically construct the scenes through representative simulation to verify the plausible causes. This serves as our primary motivation to develop the radar emulator. The novel aspects of this work are the realistic trajectory derivation, which is based on physical air-drag model, and the representative diversity of RCS contributions from each debris particle, developed through a realistic polarimetric RCS modeling and anechoic chamber measurements.","PeriodicalId":376019,"journal":{"name":"2015 European Radar Conference (EuRAD)","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132221273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A simulated analysis of the forward-scatter cross-section (FS-CS) is carried out for a typical FSR scenario where a movable target crosses the baseline. In addition to the known far-field conditions, the results are presented also for the significant near-field Fresnel region, based on a suitable numerical evaluation of the diffraction integrals as a function of the geometrical and physical parameters involved. According to a basic modeling approach, the overall FS amplitude and phase signature of typical conductive targets have been evaluated in terms of their size and distance to the antennas. The above investigations allow not only for an accurate analysis of the forward scattering problem but also for a physical insight on the performance of the FSR in near-field conditions.","PeriodicalId":376019,"journal":{"name":"2015 European Radar Conference (EuRAD)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133073029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
